背棘 (总数) : 11 - 17; 背的软条 (总数) : 10 - 11; 臀棘: 1; 臀鳍软条: 19 - 20; 脊椎骨: 35 - 36. Diagnosis: Medium fusiform tripterygiid, less than 4.0 cm SL. Dorsal fin III + XII-XIV + 10-11, first fin low; anal fin I + 19; pectoral rays 16 (1+8+7); pelvic fin I, 2, spine short and hidden, segmented rays simple, partially united by membrane. Vertebrae 10 + 25-26.

Mandibular pores 5+1+5. Snout short, profile blunt. Head length 3.7 in SL; eye 2.9; maxilla 2.3 in HL. Male overall brown with vertical bars reddish brown extending to midline; dark brown blotches and smaller bluish-white spots along midline. Female head white with brown spots; body cream with 6 pairs of semi-bars. Geographical variation in coloration and meristic characters: fishes from Mauritius have less pigmentation than those from Comoro and Seychelles Islands. Caudal vertebrae 26 in Mauritius, 25 in Comoro and Seychelles Islands. (Ref. 75031).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Adults occur in a wide array of habitats; clear and turbid water, between 0-20m depth, amongst coral rock and rubble with some sand, and in a high energy tidal environment amongst large boulders and coral heads (Ref. 75031). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
